The dummy Pstream library cannot be used in parallel mode
 

Hello everyone,


I tried to run an OpenFoam case with interFoam in parallel and got the following error :


"FOAM FATAL ERROR: (openfoam-2012)
The dummy Pstream library cannot be used in parallel mode


From static bool Foam::UPstream::init(int &, char **&, bool)
in file UPstream.C at line 50.
"


I read some threads on this forum about it but could not find a solution.


I also have more information about the MPI:


echo $WM_MPLIB: OPENMPI
echo $MPI_ARCH_PATH: /xxx/ThirdParty-v2012/platforms/linux64Icc/openmpi-4.0.3
ls -l $MPI_ARCH_PATH: ls: cannot access '/xxx/ThirdParty-v2012/platforms/linux64Icc/openmpi-4.0.3': No such file or directory
which mpirun: /opt/intel/2019.4.070/impi/2019.4.243/intel64/bin/mpirun


I guess my problem is that i have intelmpi and not openmpi but could not figure out how to solve it


Thank you for your help

By the way, i tried something:


I changed WM_MPLIB and now got:


echo $WM_MPLIB: INTELMPI


But when i start my simulation again, i got a new error:


Sorry! You were supposed to get help about:
mpi_init:startup:internal-failure
But I couldn't open the help file:
/xxx/ThirdParty-v2012/platforms/linux64Icc/openmpi-4.0.3/share/openmpi/help-mpi-runtime.txt: No such file or directory. Sorry!

Hope this helps you understand my issue
